。 In the crank pulley of an internal combustion engine that is attached to the tip of the crankshaft, a weight reducing part is formed on the crank pulley, and the direction in which the weight reducing part is arranged is set at the moment when the combustion pressure of the cylinder closest to the crank pulley is at its maximum. Bending vibration reduction in which the crank pulley has a damper mass that is made to coincide with the movement direction of the piston of the cylinder, and whose weight in a direction perpendicular to the arrangement direction of the weight reduction part is larger than the weight in the arrangement direction of the weight reduction part. A crank pulley for an internal combustion engine, characterized by having a dynamic damper installed therein.
